Upon hearing what Zhou Tian had said, the Corpse Demon was significantly affected. After all, if there were some wounds on its body that couldn't heal, not only would they harm it, but according to the rules of monsters, such unhealable wounds would continuously lose blood. As such, if it were made to carry such wounds, the blood loss over time would be enough to kill it.
In a certain sense, Zhou Tian's tactics were like a poison attack, lacking explosive power but causing continuous harm. Under constant blood loss, if it didn't have a way to counter Zhou Tian's attack, the HP it could lose from such an attack would be much more than that lost from other attacks of the same level.
If entities below the King Level had to face Zhou Tian's attack, their survival probability was nearly zero. Of course, monsters below the King Level posed no threat to Zhou Tian. Hence, using this tactic wasn't necessary for Zhou Tian as of now.
